BICYCLE ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 712,553, dated November4, 1902. Application filed September 20, 1901. Serial No. 75,760. (Nomodel.)

To all whom, it may concern:

Beit known thatI, IRA A.LAWRENCE, a citizen of the United States,residing at the town of Campbell, in the county of Steuben, State of NewYork, have invented certain new and usefullmprovementsin BicycleAttachments; and I do hereby declare the following to be a full, clear,and exact description of the inven; tion, such as will enable othersskilled in the art to which it appertains to make and use the same. i

This invention relates to bicycle 1attach ments; and it has for itsobject to provide a device one of which may be attached to each side ofthe rear fork of a bicycle to receive and support the rear axleyieldably, so that ease and comfort in riding the bicycle may bepromoted. i

Other objects and advantages of the invention will be understood fromthe following description.

111 the drawings forminga portion of this specification, and inwhichlike numerals of reference indicate similar parts in the severalviews, Figure l is a side elevation of a bicycle equipped with thepresent invention.

follower 7, held against outward displacement by means of the plate 8,which is attached to the base of the block and projectsbeyond the edgesof the opening. ,At one. end of the block is a lug 9, from which'extends arod 10, passed through a perforation 11 in the lug 12 at theend of theplate 5,and.upon this rod and disposed with its ends againstthe lugs is a helicalspringfl3, which. holds the block normally andyieldablyatthe lower end ofthe opening of the plate.

In practicethe plate 5 is disposed against the fork side of thebicycle-frame and is held in such position by means of clips 14, whichare passed around the side and engaged with the plate, the sliding blockbeing disposed downwardly. a i i Fig. 3 is a section taken longitudi'-'The sliding block 7 has a perforation therethrough and alining withaiperforation in the plate 8, and through thesetalining perforations ispassed the end of the rear-wheel axle of the bicycle.

It will be understood, of course, that one of these attachments isprovided for each side of the rear fork of the bicycle, so that bothends ofthe rear axle are yieldably supported. With thisconstruction itwill be seen that the depression of the rear of it the bicycle-frame isdirectly resisted by the helical springs of the attachments, with theresult that a great part of the vibrations is absorbed and ease andcomfort in riding is secured.

In practice modifications of the specific construction shown may bemade, and any it suitablematerials and proportions may be used for thevarious parts withoutdeparting from the spirit of the invention. What isclaimed is I t l The combination with a bicycle-frame including rearforks and rear tie-rods rigidly connected at opposite sides of the frameand having openings at their points of connection ably engaged intheslot. of the plate and hav- 7 ing a plate secu red thereagainst andoverlappingthe slotted plate to prevent withdrawal of the block, a lugupon the side of the block having a rod slidably engaged in theperforation ofthe lug at the end of the plate, a heliyieldably at oneend ofthe slot of the plate, 5

a brace connected to th e upper end of the plate and having aclipengaged with theadjacent fork side, and a wheelhaving an axleengaged with the blocks ofthe twoplates.-

Intestimony whereof I affix my signature in presence of two witnesses. I
